[PATCH] [LoopReroll] Refactor most of reroll() into a helper class

[James Molloy]

Hi hfinkel,

reroll() was slightly monolithic and a pain to modify. Refactor a bunch of its state from local variables to member variables of a helper class, and do some trivial simplification while we're there.

This should set the scene for some changes to the Scale/Root model to make it catch more cases.
